Regulating valve, iyo inonziwo control valve, inoshandiswa kudzora saizi yemvura.Apo chikamu chekugadzirisa chevhavha chinogamuchira chiratidzo chekugadzirisa, chigadziko chevhavha chichagadzirisa kuzarura nekuvhara kwevhavha maererano nechiratidzo, nokudaro kugadzirisa kuyerera kwemvura uye kudzvinyirira;kazhinji inoshandiswa kupisa , gasi, petrochemical uye mamwe mapaipi.
Stop valve, iyo inozivikanwawo sevhavha yekumisa, inogona kuvhara zvachose chigadziko chechigaro chevhavha nekushandisa kudzvinyirira nekutenderera tsinde yevharuvhu, nokudaro kudzivirira kuyerera kwemvura;mavharuvhu ekumisa anowanzo kushandiswa mugasi rechisikigo, liquefied gasi, sulfuric acid uye mamwe gasi anoparadza uye mapaipi emvura.
Ivhavha yegedhirakafanana negedhi.Nekutenderedza dzinde revharuvhu, ndiro yegedhi inodzorwa kuti ifambe yakamira ichikwira nekudzika kudzora mvura.Zvindori zvekuisa chisimbiso kumativi ose egedhi ndiro inogona kuvhara zvachose chikamu chose.Ivhavha yegedhi inogona kuvhurwa zvakakwana uye yakavharwa zvakakwana, uye haigoni kushandiswa kugadzirisa kuyerera.Mavharuvhu egedhi anonyanya kushandiswa semidziyo yekubira mumvura yepombi, tsvina, zvikepe uye mamwe mapaipi.
The swing check valveinotsamira pakumanikidzwa kwemvura kuvhura chivharo chevhavha.Kana dzvinyiriro yemvura iri muvharuvhu inopinza uye pombi dzekubuda nayo yadzikama, chivharo chevharuvhu chinogona kuvhara negiravhiti chayo chega kudzivirira mvura kuti isapfuure.Basa rayo guru nderokudzivirira kuti mvura irege kuyerera ichidzoka.Kuyerera, ndeye otomatiki valve chikamu;inonyanya kushandiswa mu petroleum, makemikari, mishonga uye mamwe mapaipi.
